| 摘 要： | 制备了硅含量分别为0％，0．2％，0．5%，0．9％和1．2％的五种Fe-6Al合金，并研究了这五种合金在淬火状态下的微观组织特征和阻尼性能，分析了硅含量对铁-铝合金阻尼性能的影响。结果表明：当硅含量为0．5％左右时，Fe-6Al减振合金具有适当的晶粒尺寸，阻尼性能最好。

| Abstract: | Five kinds of Fe-6Al alloys with different Si contents were experimentally made. The internal friction and microstructure of the alloys under water quenched conditions were investigated. An internal friction peak was observed in the present alloys. The internal friction peak reach the highest value when the Si content increased to 0. 5%, which is found to be directly attributed to the proper crystal grain from the aluminium alloy matrix. |
